WILLIAM JOHN DOYLE, OF MERRIOKVILLE, CANADA.

STONE-LIFTlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 566,745, datedSeptember 1, 1896.

Application led September 3, 1895. Serial No. 561,267. (No model.)

To @ZZ whom it may concern:

Be it known that LWILLTAM JOHN DoYLE, a subject of the Queen of GreatBritain, and a resident of Merrickville, in the county of Greenville,Province oi' Ontario, Canada, have invented certain new and usefulImprovements in Stone-Lifting Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to improvements in machines for lifting andtransporting stones, and is designed more especially for use on farms,whereby large stones may be removed from the iield and conveyed to anydesired point to build a fence.

The object of the invention is to provide an improved construction ofthe same whereby I secure important advantages with respect toefficiency in operation.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a machineconstructed in accordance with my invention. Fig. 2 is a centrallongitudinal section of the same. Fig. 3 is a plan view. Fig. a is adetail sectional view or" the front axle and bolster.

In the said drawings,the reference-numeral 1 designates the front axle,with which the tongue 2 is connected; 3, the rear axle, and 4L thewheels. At the front of the machine is a bolster 5, connected with thefront aXle by a king-bolt 6, which passes through a circular hole in thebolster and also through a tapering slot in the axle. The object of thistapering slot is to allow the king-bolt to play therein, so that inturning on uneven ground there will be no liability of the kingboltbreaking, which is frequently the case when straight holes or holes ofthe same size throughout are used to receive the lower end of theking-bolt. Secured to the said bolster are upright-s 8, inclinedslightly to the rear and contracted at their upper ends, which areconnected together by a cross-bar 9. Secured to said uprights are tworearwardlyextending beams 10, the rear ends of which are separated orspread apart and are secured to standards or uprights 12, which inclineslightly forward. These standards or uprights are connected together bya crossbar 13 and their lower ends secured to the rear axle.

Journaled to the beams l is a windlass 14, to which is secured one endof a chain 15, the opposite or free end of which is provided with a hookor grapnel 1G. Secured to one end of the windlass is a drum consistingof a ring 17, to which are secured on opposite sides two diam etric bars18. The bars on one side are at right angles to those on the other, andsecured thereto at the centers thereof are metal plates 19, formed withangular holes 20,through which the correspondingly-formed end of thewindlass passes, so that as the drum is rotated the windlass will rotatetherewith. The ends of these bars project beyond the periphery of thering, and are beveled on their inner sides to form guides for a ropesecured thereto. Short bars are also secured to both sides of the ringat suitable points with their ends beveled and projecting beyond theperiphery of the ring similarto the ends of the bars 18. The rope 20h,secured to the drum, is wound thereon and its free end passes through asheave or blocl: consisting of the yoke 2l, pulleys 23, and a hook 24,and at its extremity the rope is provided with a hook 25. The hook 24 isadapted to engage with an eye 26 on the end of the front axle, whilehook is adapted to engage with the whiffletree, to which thedraft-animals are connected.

V The numeral 27 designates brace-rods, 2S a transverse snubbing-bar onthe front uprights upon which the rope is wound when a stone has beenlifted or elevated, and 29 a pick carried by the cross-bar of the rearuprights or standards for drilling holes in rocks.

Passing through guides 30 in bars 31, secured to the beams 10, is atransverse locking-bar 32, one end of which is adapted to engage withone of the bars in the inner side of ring 17 and prevent rotation of thedrum. A lever 34 is pivoted to this bar for throwing it into and out ofengagement with the drum. This lever is fulcrumed to an arm 34a,fulcrumed to one of the beams 3l.

ICO

The operation is as follows: The grapnel of thel Wi-ndlass-chain isconnected with the stone to be raised in any manner found convenient andthe sheave of the block of the drum-rope connected with the eye on thefront axle. The locking-bar 32 is then pushed back out of engagementwith the drum and the hook 25 of the rope engaged Wit-h the Whiftletree,to which the draft animals are Io connected. By now driving the animalsfor- Ward the rope will be unwound from the drum, rotating the Windlassand causing the chain to be Wound thereon, and the stone lifted. Thelocking-bar is then actu ated by the lever to engage with and lock thedrum, and the end of the drum-rope is disengaged from the Whiiiietreeand Wound several times upon the bar 28. The animals are then hitched tothe machine and the stone transported to Where l. In a stone lifting andtransporting machine, the combination with the axle, the Wheels, thestandards and the beams, of the Windlass and chains, the drum consistingof the ring, the bars on opposite sides thereof, having beveled endsprojecting beyond the periphery of the ring the plates secured thereto,the short beveled bars, the rope secured to the rim, the hook on the endof the rope, the pulley and its hook, substantially as described. v

2. In a stone lifting and transporting mam chine, the combination withthe aXle, the Wheels, the standards and the beams, of the Windlass andchains, the drum consisting of the ring the bars on opposite sidesthereof, having beveled ends projecting beyond the pe riphery thereof,the plates secured thereto, the short beveled bars7 the rope secured tothe rim, the transverse lcckingbar and the lever connected therewith,substantially as described.

In testimony that I claim the foregoing as my own Ihave hereunto affixedmy signature in presence of two Witnesses.

WILLIAM JOHN DOYLE.
